Log Message:
Introduce a new function, uvm_lwp_is_pagedaemon(), which returns true
if the specified LWP is the pagedaemon LWP.  This test is inline for
the kernel proper, and directed to a function for modules.  This, in turn,
allows us to hide "struct uvm_cpu" and "struct uvm" from modules, as
these have arrays in them that are not a consistent size certainly across
$MACHINEs within a given $MACHINE_ARCH, and may not necessarily even be
consistent within a given $MACHINE.

NetBSD -> 11.99.6 because new symbol referenced by modules.
